Bug ID: 33536
Summary: LLVM Assertion failure with
new-experimental-pass-manager and ThinLTO
Product: libraries
Version: trunk
Hardware: Other
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Interprocedural Analyses
Assignee: unassignedbugs at nondot.org
Reporter: kbarton at linux.vnet.ibm.com
CC: llvm-bugs at lists.llvm.org
The following test case causes an assert on PPC64LE Linux using the
experimental pass manager and ThinLTO:
namespace std {
template <typename _CharT, typename = _CharT> class basic_ofstream;
typedef basic_ofstream<char> ofstream;
template <typename, typename> class basic_filebuf { virtual int sync(); };
template <typename _CharT, typename _Traits> class basic_ofstream {
typedef _CharT char_type;
typedef _Traits traits_type;
typedef basic_filebuf<char_type, traits_type> __filebuf_type;
__filebuf_type _M_filebuf;
};
}
std::ofstream out_file;
Compile Command:
/home/kbarton/llvm/build/dev.github//bin/clang++ -c -o example.o -m64
-fexperimental-new-pass-manager -flto=thin -O2 -mcpu=power8 example.i
